Philibert never proposed any sort of general classification. It should be noted, though, that Philibert primarily based his conclusions on the observations of acrocarpous mosses. He did discuss pleurocarps in the more general articles (especially those on the endostome), but his primary data were from acrocarps. However, he presented principles npon which a classification could be constructed. 

Subterminal branches are sympodial branches that develop just below a terminal gynoecium or androecium. Subterminal branching is especially common in acrocarpous mosses, and in many groups most of the shoots are just a series of subterminal branches (e.g., Pottiaceae, Grimmiaceae). Subterminal branches, or secondary axes from the basal part of perichaetia in cladocarpous mosses, are present in many members of the Hypnales (La Farge-England, 1996), but their role in the plant architecture is almost never comparable with that of ordinary branches.

The following architectural characters were originally derived from examination of a wide range of pleurocarpous and acrocarpous mosses for cladistic study of the evolution of the pleurocarpous mosses (De Luna et al., 1999 Newton and De Luna, 1999), and have subsequently been further modiiied in connection with studies of the early diverging lineages of pleurocarpous mosses (see BeU and Newton, 2004, 2005, and Chapter 3). 

Acrocarpous Having terminal fruit, or more particularly mosses bearing the sporo-phyte terminally. 

In Rhizogonium and Pyrrhobryum Section Pyrrhobryum, innovations on the perichaetial modules form new perichaetial modules (Figure 14.5B), but not vegetative primary modules (discussed further in Chapter 3). The placement of these taxa in the pleurocarpous mosses, in a basal grade containing several acrocarpous taxa (BeU and Newton, 2005, see also Chapter 3), could indicate that the presence of subperichaetial innovations in these taxa is a retained plesiomorphic condition, whereas in taxa such as Amblystegium this condition is an independently derived reversal. 

Mesozoic records of mosses are surprisingly few. As with the Palaeozoic ones, most of them are either acrocarp-Uke, or not very well understood due to poor material preservation. One Triassic...
